What programmer do you use? I think you have a problem with that...

I have a CH341A Programmer. Not the best and I am planning to buy a better one, but in the meantime I have just flashed 8x 840 G3. And with the new chip I was able to perform a proper write and read. I think the friend who tried to unlock it did more damage to it doing so.

Thank you aboumohamed and aldopc,

I tried your files and they did not work. I still get a black screen with the fan spinning.
I had to replace the 32 MB Chip since I was not able to read/write on the old one.

Hey there,

I have got a HP Elitebook from a friend. It just starts with a black screen and loud fan. He tried to unlock the BIOS. Strangely I can't get 2 same reads out of the 32 MB Chip.
If I put another Chip in I can read and write on it without any problems. So I suggest it is a bad chip.
I only got a faulty readout of the 32 MB. The original dump and the one that was flashed is sadly gone forever. But maybe someone can make a working image again out of it?

Thanks a lot in advance

I have rebuilt your original bios, write both chips with these files and copy the result.
